An image pickup apparatus is mountable with a lens apparatus including a first optical image stabilizing unit configured to move an optical element that is a part of the imaging optical system, in a direction intersecting an optical axis of the imaging optical system. The image pickup apparatus includes an image sensor, a second optical image stabilizing unit configured to move the image sensor in a direction intersecting the optical axis, and a control unit configured to control the second optical image stabilizing unit based on an image stabilizing reference position of the first optical image stabilizing unit which is a reference position for an image stabilization of the first optical image stabilizing unit.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image pickup apparatus according to claim 1, wherein the control unit controls the second optical image stabilizing unit further based on information on a rear principal point position and an image magnification.
3. The image pickup apparatus according to claim 1, wherein the instructions cause the at least one processor to function as an acquiring unit, and the acquiring unit acquires information on the image stabilizing reference position of the first optical image stabilizing unit by communicating with the lens apparatus.
4. The image pickup apparatus according to claim 3, wherein the information on the image stabilizing reference position includes at least one of information of the image stabilizing reference position and information on a model of the lens apparatus.
5. The image pickup apparatus according to claim 1, wherein the image stabilizing reference position is a rotation center position of a shake applied to the image pickup apparatus.
6. The image pickup apparatus according to claim 1, wherein the control unit controls the second optical image stabilizing unit so as to reduce a parallel-movement shake amount of the image stabilizing reference position caused by moving the optical element by the first optical image stabilizing unit.
8. The image pickup apparatus according to claim 7, wherein when the lens apparatus includes the first optical image stabilizing unit, the acquiring unit acquires information on an image stabilizing reference position of the first optical image stabilizing unit which is a reference position for an image stabilization of the first optical image stabilizing unit, and the control unit controls the second optical image stabilizing unit based on the image stabilizing reference position of the first optical image stabilizing unit acquired by the acquiring unit.
9. The image pickup apparatus according to claim 8, wherein the information on the image stabilizing reference position includes at least one of information of the image stabilizing reference position and information on a model of the lens apparatus acquired by the acquiring unit.
10. The image pickup apparatus according to claim 7, wherein the image stabilizing reference position is a rotation center position of a shake applied to the image pickup apparatus.
11. The image pickup apparatus according to claim 7, wherein the control unit controls the second optical image stabilizing unit so as to reduce a parallel movement shake amount of the image stabilizing reference position caused by moving the optical element by the first optical image stabilizing unit.
14. A non-transitory computer-readable storage medium storing a computer program that causes a computer to execute a control method according to claim 12.
15. A non-transitory computer-readable storage medium storing a computer program that causes a computer to execute a control method according to claim 13.
